Dislocate — disconnect and reconnect processes

Synopsis

dislocate [ program args... ]

Introduction

Dislocate allows processes to be disconnected and reconnected to the terminal. Possible uses:

Usage

When run with no arguments, Dislocate tells you about your disconnected processes and lets you reconnect to one. Otherwise, Dislocate runs the named program along with any arguments.

By default, ^] is an escape that lets you talk to Dislocate itself.  At that point, you can disconnect (by pressing ^D) or suspend Dislocate (by pressing ^Z).

Any Tcl or Expect command is also acceptable at this point. For example, to insert the contents of a the file /etc/motd as if you had typed it, say:

     send -i $out [exec cat /etc/motd]

To send the numbers 1 to 100 in response to the prompt "next #", say:

     for {set i 0} {$i<100} {incr i} {
         expect -i $in "next #"
         send -i $out "$i\r"
     }

Scripts can also be prepared and sourced in so that you don't have to type them on the spot.

Dislocate is actually just a simple Expect script.  Feel free to make it do what you want it to do or just use Expect directly, without going through Dislocate. Dislocate understands a few special arguments.  These should appear before any program name.  Each should be separated by whitespace.  If the arguments themselves takes arguments, these should also be separated by whitespace.

The -escape flag sets the escape to whatever follows.  The default escape is ^].

Caveats

This program was written by the author as an exercise to show that communicating with disconnected processes is easy.  There are many features that could be added, but that is not the intent of this program.
